I am looking for a server side PDF tool that provides various PDF services to ASP.NET applications.

We have a common need to programmatically open and manipulate PDF files in a ASP.NET web application.

Specifically, we want to:

1. With existing PDF files, enter info into text fields on the PDF and

capture that data to write back to a database

2. Create new PDF documents on the server with data from a DB

3. Populate existing PDF form fields with data from a DB

All PDF's are created using Adobe Lifecycle Builder.

LiveCycle Forms will do what you need, but it is a J2EE application. To use it you need to set up a J2EE application server. If you're willing to do that, you can access it via SOAP using a .NET server using a dll that Adobe provides.

Can you please provide more details on that.

Also, can you tell me where I can find a sample for reference.

I wrote a test C# web application (with a lot of guidance from a SmartDoc Technologies article and the Adobe "Developing Custom Applications" document) that displays a page which contains a pdf document. You can display a pre-populated PDF by entering data as html input. You can also change the data on the PDF, and extract the data and display this information.<br /><br />Download the sample code from the Developing a .NET web application using Adobe LiveCycle Forms article at http://www.smartdoctech.com/articles.aspx.<br /><br />Place your PDF file on the LiveCycle Forms server.

The html I supplied got mangled. If you are desperate, then view the source on this page an do a find on Default.aspx UI CODE.

Is there any shortcut way to show the PDF stored in Oracle database as BLOB in a web browser using ASP.NET? (VB not C#)?

No involvement of XML and using data reader.

Former Community Member

I have the following code to create the pdf file in the same browser


Response.ContentType = "application/x-pdf"

Response.AddHeader("Content-Type", "application/x-pdf")

Response.AddHeader("Content-Disposition", "attachment;filename=Record.pdf")

Response.AddHeader("Content-Length", "Record")

I am getting the file(Record.pdf) but only blank file not with the form text value
